As of April 2025, citizens of 41 countries can enter the United States for up to 90 days without a visa through the US Visa Waiver Program (VWP). India is not included in the VWP, so Indian nationals must apply for a US visa through the normal procedure. To travel under the VWP, travelers must hold a valid e-passport, obtain an approved ESTA, plan a stay of 90 days or less, and possess a ticket for return or further travel. The ESTA approval does not guarantee entry, and travel history and passport validity are also important factors. The VWP offers a streamlined path for eligible citizens to visit the US, while others must go through the traditional visa application process.
